This invention-relates toblowvtorches par? ticularlylthose ofthe readily portable type,A gandxhasfor itsF object the'provision ofA a' novel ,blovv torch! designed 'particularly for use by electricians"andothers, the .device being vso constructed and arranged 4that it may be readily carried aboutfin a tool. boX `orin theusers .pocketand capableof being` set down ory laid down yupon a support with-l out likelihood of its falling ofi' and beoona` ing subsequently damaged as. a result thereof. c. ll i `An'important Objectis theprovisi'on of' a blow torch :which is adapted to use alcohoh' gasoline orv the like as a fuel, thedevice eni- `bodyng a wick dipping down into the fuelY reservoir so that` a `constant feeclof fuelA Willfbe suppliedto the flame, andanotherx feat-ure .being the provision Yof a bloiv pipe discharging adj acent the-"flame and ,adapted to rhave air forced therethrough by the-lungs of theuser whenever it isnecessary to pro'- f i vide a very hot` Aflame for solderingor other.

similar purposes. y. f Another objectofthe. invention, is to pro-v vide a'device of` this character `which ispro.-l vided with iiint andr steel means :whereby ignition .may be readilyleifectech it being consequently unnecessary that the 'operator be provided Withniatches inorderto start the device. t f i ,e l e An additionahobject isto provide ,afde-` vice ofithisy character'which Willbefsim-ple'. and inexpensivein manufacture, easy to use, positive in. action, eflicientl and durable in service, and .a general'.improvementiin` the art. u

With the vantages in view,.the invention consistsin the details of construction, and thearrangement and combination of parts to .be here-` inaftervfmore fully described andclaiined, and illustrated in the accompanying drawings,inrvvhich:

Figure l is a vertical longitudinal section taken through the device.

Figure 2 is an edge elevation, and

Figure 3 is a bottom plan view.

Referring more particularly to the dra-W- ings, I have shown the device as comprising a main casing 10, which is constructed preferably of suitable sheet metal enameled, nickel-plated or otherwise treated to4 have a pleasing appearance and to bei freefrom likelihood of corrosion or rusting. This casing l0 is preferably rectangular in shape,'

.above and other objectsand ad-4 so thatl in case Yit is laid down uponA the topy of `a step-ladder or bench or other support, it cannot roll 'off as would bethe .case if it Wereof cylindrical or other curved cross sec# tionalshapel Clearly,` this casing 10 may be constructed in one piece "or 'in Vany desired number of pieces to be secured together asV by soldering'welding or thelike, there be` ing absolutely no 'limitations in this Vrespect inasmuch as these pieces are purelyl lnechan'- ical. details. At its top' Wall 111, this casing l0 is providediwith an opening surrounded I byA an upstanding flange l2- and Within thisopening is mounted the burnerv structure to be described. i

i The casing l0 constitutes a reservoir `with-V in which, is `contained a suitable supplyof fuehsuchas alcohoh-gas0line or th'elike, the former being probably preferable asbef ing less likely to explode. .1 Theinterior of the flange lQ/is threadedfand.screwed there? intois al thiinble 13of cylindrical forin'pro.- videdL intermediate its endsfwith an angular portiony ll for the purpose yof facilitating an engagement of awrench thereon forcturning purposes; .Thiscthinible entends'v partly into the casing and ,partly abovethe saine and: is of course ,provided ivithan opening therethrough `Within which is kmounted ,a sleeve v15 fwliich, constitutes a carrier `or guide forr a Wick 16 Aof ,anybrdinaryfor preferred type, the intention being that the upperfend of the `Wick l extend labove ogr,` ,beyond .the sleeve 15` so as to permit coinbustionfat this point.A Thelength of the wick may ofcourse be varied .and will vary as it fisfusedolV burnedY away butV initiallyit, is intendedfto be Aof specific lengthto extend down into the casinglO and possibly even lieupon the bottom thereof, Athis-.detail being immaterial',

It .is preferablek tli'atthe guide .sleeve l5 be provided 'at itsbottoin Withopenngs 17 and near its upper portion, vwith other openings 18:,` ,the latter being providedfor thejpuri-f Ypose of preventing the fuel in liquid stage sleeve 15.

member 2O connected at one endwith theA hood or cap having its other end connected with the casing 1() for the purpose of preventing the cap or hood from becoming lost.

An important feature is the provision of a blow pipe which includes or comprises a tube 21, preferably of metal mounted upon the side of the casing l() as by clips 22 and bent or shaped to have its upper end portion disposed adjacent the Wick guide or rlhis upper end of the tube 21 is closed as shown at 23 but is provided at one side with a hole 2l located opposite the end of the wick so that when air pressure is supplied to this tube, the air will pass out therefrom and transversely across the flame at the end of the wick. A suitable rubber tube or hose 25 is connected with the tube 21 and may be placed in the mouth of the operator whenever it is necessary that he have a forced draft to obtain a blast effeet. Clearly, if compressed air is available the rubber tube 25 may be connected with the source of compressed air instead of being blown into by the operator.

Another important feature of the invention is the provision of igniting means which will make the use of matches unnecessary. In carrying out this detail, I provide a block or piecer of Hint 26 mounted within a. frame structure or bracket 27 located on one side of the casing l0, this bracket or frame structure being formed with an opening 2S exposing a considerable area of the flint. This igniting feature also comprises a tubular supporting member 29 adapted to be screwed into a threaded opening formed in a flange 30 in the top of the casingwhen it is not in use, the member 29 having a knob or other similar handle 31 at its upper end and having its lower end carrying a piece of hard steel 32. The member 29 is of tubular form and is adapted to be filled with absorbent material capable of being saturated with alcohol, gasolineor the like, the materialenposed adjacent the hard l steel point 32. Clearly, when the device 29 is removed from the casing and the hard steel point 32 rubbed or struck upon the flint 26, a spark will be produced which will ignite the absorbent packing and producey a sufficient flame to effect ignition of the main wick 16. When the wick 16 is burning, or when a flame exists at the upper end thereof, it is clear that this fiame may be used for soldering purposes and in case of necessity the operator may blow through the tube 25 in order to get a blast ell'ect which will readily effect melt-ing of any solder necessary to use.

Another feature of advantage is that the device provides or embodies a support so that it cannot be readily tipped over. This may consist simply of an elongated spring member 33 pivoted at St'upon the bottom of the casing 10 and normally lying within a recess 35 formed by striking the bottom upwardly or inwardly, this spring 33 being capable of being sprung and moved transversely into the position shown by dotted lines in Figure 3 so as to make the device more stable when setupon a table, top `of a step-ladder or other support.

From the foregoing description and a study of the drawings, itwill be apparent that I have thus provided a very simply constructed, inexpensive and easily operated and controlled device for the purpose specilied, which will possess all the features of advantage set forth. It is really believed that the construction, operation and advan tages will be readily apparent to one skilled in the art without further explanation.

While I have shown and described the preferred embodiment of the invention, it should be understood that I reserve the right to make such changes in theform, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claim.

Having thus described' the invention, I claim:

In a torch of the character described, a casing serving as a fuel reservoir, a thimble detachably mounted within the top of the casing, a guide slidably mounted within the thimble. a wick within the guide, and a blow-tube mounted exteriorly upon the casing in longitudinal relation thereto and having one end closed and terminating adjacent the wick, said tube being formed in its side toward the wick with an air discharge opening whereby a current of air may be forced transversely of the iiame at the wick.

In testimony whereof I affix my signature.
